AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

Thanks, Daniel! I found the problem. The scanning plans for the two scans were not identical. This could be the mistake by the scanning technician.

BTW, I think I found a bug in 3dinfo.
When I run "3dinfo -extent FILE1" and "3dinfo -extent FILE2", it shows the extent information correctly; when I run "3dinfo -extent FILE1 FILE2", it shows the extent information for the two files with the extents from FILE1.
My AFNI version is 18.0.11.

Below is the terminal information.
